CygWin/gcc-3.4.4 updates.
I replaced my cygwin compiler with 3.4.4, did a make clean of plib, simgear,
and flightgear, then did a make install of all three. With the included changes,
everything builds fine, and runs fine.
or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.
Attached is a patch to add oil temperature to the YASim piston engine
model. This brings to life one of the pa28-161's otherwise 'dead'
guages. It's a pretty simple 'model' based on temperatures and warmup
times I've observed in the labs on auto engines and run through my
dodgy-memory filter. It does the job of populating the guage with
something plausible though.
Auf Niederlandisch:
Bij deze de patch voor de taxiway code. Deze code is nog gebaseerd
op de bestaaande architectuur, gebaseerd op de FGAirport class in simple.[ch]xx
Ik heb me voornamelijk gericht op nieuwe functionaliteit; de volgende
submissie zal waarschijnlijk bestaan uit opschoning, opsplitsing en een
implementatie van de nieuwe airport architectuur, zoals voorgesteld door
David Luff.
En Anglais:
Here is the patch for the taxiway code. This code is still based on the
exsisting architecture, which is based on the FGAirport class in simple.[ch]xx
I've aimed mostly at new functionality; The next batch will probably contain
code cleanups, splitups and the implementation fo the new airport architecture,
as proposed by David Luff.
I have corrected a few bugs with the owner draw gauge, weather radar code and heat-haze effect.
- od_gauge.cxx :
corrected a rendering bug where the generated texture was only visible
from a certain angle or distance ;
corrected the search of textures inside the aircraft scene graph ;
- wxRadar.cxx :
the echo of clouds was lost when the pilot was not looking in the
plane direction ;
Using new gcc 4.0 I have some serios warnings about uninitialized
variables, that are used. I created a patch, but I have no idea if it
is possible to do it my way. Can you check this out please?
Erik: I've modified the patch slightly based on the contents of an older
version of hitlist.cxx. I think this is correct now.
modeling of a simple single vacuum system with a pump source on each engine
in a multiengine aircraft. The highest rpm engine takes priority for driving
the vacuum system.
I had a quick view over the ssgBase::ref() calls in flightgear.
I made them all symmetric and used ssgDeRefDelete to dereference them.
This has the basic advantage that ssgDeRefDelete additionaly deletes the
memory instead of just decrementing the reference cound without deletion ...
This includes an incorrect deref instead of a ssgDeRefDelete in the placement
transform registration I introduced earlier. I believe that this causes the
problems with long flights (unverified, but with a big propability).
it for the B-29). The gear model itself has supported this always,
but there was no interface from the XML file. Should be backwards
compatible. I don't think I broke anything...
I have done a valgrind run in flightgear. Just start it up and close it at the
fist change I had about half an hour later.
source-leak.diff:
Also two minor ones, but leaks ...
I stumbled across two memory errors with two wrong const references to
std::string.
As I fixed that, I also moved aircraft_dir which is only used from UIUC into
UIUC. With that uiuc_aircraftdir.h is empty and can be removed.
I believe I have found the agl hud problems as well as the 'hole' in the
carrier's deck. I spent half the day to reproduce that problem, it did not
occure when you start on the carrier not does it occure with JSBSim and my
really often used testaircraft. So I really need to improove my helicopter
flying qualities.
I was under the impression that *all* FDM's call
FGInterface::updateGeo*Position(..)
so set the new position in the FDM interface. Therefore I had added at the
some code that updates the scenery elevation below the aircraft to *those*
functions.
Ok, not all FDM's do so :/
The attached patch factors out a function computing the scenery altitude at
the current FDM's position. This function is also used in those FDM's which
need to update this value themselves.
Also this patch restores the nearplane setting and uses the current views
altitude instead of the current aircrafts. I think that this should further
be changed to the eypoint's agl in the future.
The agl is again ok in YASim's hud.
Changes
=======
- acmodel.cxx :
we now have an optional new property (/sim/model/texture-path) that is used
as the first path in wich aircraft textures are searched. If textures are not
found there then the usual texture path or model path is used ;
This allows to replace only needed textures for liveries ;
- options.cxx :
added a new --livery=xxx option for the user pleasure ;
this will just set the /sim/model/texture-path property with /livery/xxxx
- od_gauge.cxx, og_gauge.hxx, cockpit.cxx, cockpit.hxx,
generic-instrumentation.xml :
added an helper class that contain a rendering context for glass instrument
or any other opengl drawn instrument ;
- wxradar.cxx, instrument_mgr.cxx, wxradar.hxx :
first experimentation of a weather radar ;
This adds a TACAN instrument to the inventory. Range and bearing are calculated
to the TACAN or VORTAC beacon selected by means of the Channel Selector in the E
quipment/Radio pull-down menu.
A TACAN beacon has also been added to the aircraft carrier Nimitz (channel #029Y
).
passing it along to FlightGear.) I notice that the serial port read only
seems to work correctly if I read one character at a time. Multicharacter
reads seem very unreliable.
I've prepared a patch as suggested by Hans-Georg Wunder and Jeff McBride.
In addition I've removed the ability to completely leave out the integral
action by setting Ti to zero. The velocity form of the PID algorithm _needs_
the integral action.
